Which Nim Paradigm could I use instead of OOP with Generics and Inheritance?

Even though there is a warning for generic methods they do work in my 
experience. Otherwise you could do pointer proc interfaces where you abstract 
all procs into `proc(_: Widget, ....)` then inside do like
    
    
    proc label(str: string): Widget =
      Label(
        str: str,
        drawProc: (proc(widg: Widget, ...) =
      let widg = Label(widg))
     )
      ....
    
    
    Run

Though if you really want to go into the deep end you could do full static 
dispatch heavily using generics and concepts like I do with
